Transport is not up and running in 3 node cluster 6.8.0

Elastic Stack Elasticsearch
1

Hi,
I have 3 node cluster, and my elasticsearch.yml

----------------------------------- Node -------------------------------------

node.name: "machine1"
node.master: true
node.data: true
search.remote.connect: true

#---------------------------------- Network ------------------------------------
network.host: "10.198.238.142"
http.port: "9200"
transport.tcp.port: "9301"

....
....

--------------------------------- Discovery ---------------------------------

discovery.zen.ping.unicast.hosts:

  • "10.198.238.142:9301"
  • "10.198.238.4:9301"
  • "10.198.238.6:9301"
    discovery.zen.minimum_master_nodes: 3

bootstrap.memory_lock: true

Wrote a playbook to elastic stop and stop via systemctl commands. only 1 node comes back with transport port on 9300 or 9301.
But another 2 nodes are not up with transport port.
